PiggyHead my game theory is that during morning and day, if you play qick mtch, you may be matched with so-called "sweats" and "tryhards", because those should be people without job. i know some competitive losers who play after they wake up.
playing at evening is better by default for most people, as it's best to do your tasks first before you relax, but knowing the time when "sweats" play will be helpful to people, who dont want to match with them
